Title: Magnetic ceiling, wall and floor coverings - allowing application without paste in shorter time and at lower cost
Inventor: BESENDAHL WOLFGANG
IPC: H01F1/00
Filed: 1975-07-23
Abstract: Ceiling, wall or floor coverings are applied by applying to the corresponding surfaces a coating consisting of an adhesive carrier and permanently magnetic fine powder magnets. After the adhesive carrier has dried, wall paper and other coverings incorporating Fe powder can be applied to the surfaces which are now magnetic. The magnets practically never lose their attraction, so that treatment of the surfaces is required only once. The coverings can thus be applied without fastening means and without paste or adhesive, in a shorter time and at lower cost. Method may be applied to wall paper, floor coverings, ceiling coverings, picture frames, posters, decorations and wall hangings; also furniture and technological instruments (i.e. veneering operations).

Title: Table football game with graded goals - has hand-operated kicker which kicks balls into goals given different numerical values at table end
Inventor: HELLER LUDWIG
IPC: A63F7/06
Filed: 1975-09-01
Abstract: This football game is a table game and has a footballer figure which can be made to kick a ball into goals of varying values on a board at the table end. Non-scoring shots run down into a gully to keep them away from the kicker so that the ball can only be kicked once. A football on the front wall of the table can be hit in any way so that, by a system of levers, inside the table, the kicker's leg is swung forward to kick a ball. A lever is provided to turn the kicker to vary the direction in which the ball is kicked. This appts. can be used for fairground stalls as well as indoors, in public houses, for use by people of all ages.

Title: Telephone dialling system with numbers store - extracts number from store and checks it before engaging line equipment
Inventor: SCHOEN SIEGFRIED
IPC: H04M1/27495
Filed: 1976-04-27
Abstract: The circuit dials selected telephone numbers, automatically checks the number extracted from a memory by optical display, with a separate key (AKT) for checking. When the key is depressed, followed by operation of the main selector key ZT to extract a number from the memory, the number to be dialled is displayed, but not fed to the line for dialling. A second operation of the main key dials the number after checking that the correct number has been selected according to the optical display. The arrangement reduces the time during which the subscriber's line is actually held, and does not block it for incoming calls during the period needed for selection and checking.

Title: Exhaust gas feed back regulator - has depression switch over valve to alter fuel mixture ratio and interrupt exhaust feed back
Inventor: ONAKA HIDEMI
IPC: F02D21/08
Filed: 1976-06-22
Abstract: The exhaust gas feed back is regulated by a depressions switch over valve provided with one inlet union, two outlet unions and regulator inlet. The switch over valve contains two diaphragms which cause the inlet to make connection with the outlet to the fuel regulator valve and at the same time interrupt the connection between inlet and the second outlet leading to the exhaust return valve. The result is that no exhaust gas is fed back to the engine and a leaner mixture is established. The depression is additionally regulated by a magnetic valve which opens when the engine working temperature is below 60 deg.C, or the vehicle is exceeding a pre-calculated speed or the gear change lever is in fourth or direct drive position.

Title: Coil consisting of flexible printed circuit board - has supporting foil with transversal cuttings spread out so that conducting trace is helical
Inventor: KOSCHIG ADOLF ING GRAD
IPC: H05K1/00
Filed: 1976-07-16

Title: Constant pressure charging pump for variable loads - has hydrostatic drive for hydraulic motor which operates suction pump
Inventor: SCHUETZ JOSEF
IPC: F04C11/00
Filed: 1976-08-19
Abstract: The charging pump feeds load with variable liquid demand at constant pressure. The drive motor has constant speed, and pump is used for example for filter presses whose demand is reduced as filter chambers are filled with deposits. The pump drive power losses are kept to a min. The hydrostatic drive (26) is varied by a feed pump (30) driven by the driving motor (24). The feed pump delivery rate can be varied in relation to pressure automatically for the given rotating speed of the driving motor. A hydraulic motor (32) is provided which is fed by the feed pump and this motor drives the charging pump (12). The feed pump (30) can be a vane pump with adjustable eccentricity.

Title: Carding machine control - has an electrical circuit to allow speed shifts without coupling damage
Inventor: TSUNEKAWA TAKAHIKO
IPC: D01G15/36
Filed: 1976-08-25
Abstract: The drive mechanism for the cylinders of a carding machine uses an electric control unit for the coupling between the control gear and the doffer roller, together with a control motor to modify the control gear ratios. The rotary movement of the doffer drum and the feed roller is generated by the shaft of the control gear through the coupling, if the control gear is set to the low limit value of its delivered rotary count. The design allows high speed operation of the carding process, with intermittent shifts from high to low speed rotation, and vice versa, without damaging the coupling.

Patent DE-2701010-A1 (DE)
Inventor: BAIKER ERWIN
IPC: B24C7/00
Filed: 1977-01-12
Abstract: The metering device serves for the continuous admixture of a granular product, in particular a blasting medium, in precisely metered quantities into a conveying gas stream. The grain mixture (41) passes under its own weight through the annular gap (33) and, assisted by the rounding (43), into the edge part of the cutout (29) in the counter-flange (28). A natural conical inner surface (35) is formed at this point. The height (37) of the pouring cone is defined by the inner circular edge (45) of the hollow truncated cone-shaped outer surface (11). During operation, the drive shaft (4) with the wiper arm (7) and the scraper (8) rotates at a constant speed. During this process, the scraper (8) continuously removes the bottom part of the pouring cone (34) and brings the scraped-off product into the outflow channel (31) where it is added continuously to the pneumatic transport located below it. Due to the undelayed sliding of material from the annular gap (33), a continuous, constant feeding to the pneumatic transport can take place. <IMAGE>

Title: Safety plug for electric model railway transformer - prevents unused plug remaining live when one of two parallel mains transformers is idle
Inventor: KILIAN HELMUT
IPC: H01F27/40
Filed: 1977-05-03
Abstract: Some model electric railways are provided with two transformers connected in parallel and each transformer has its own separate connections to the mains. If one of the mains plugs is disconnected the pins remain live and create a hazard. This danger can be eliminated by using a special plug (1) with pins (2, 3) connected to internal micro-switches (5, 6). When the plug is pressed into the socket (13) the plunger (14) is forced between the arms of the switches and closes the contacts. When the plug is removed from the socket the spring (9) withdraws the plunger (14) so that its enlarged end forces the arms of the switches apart and opens the contacts to disconnect the pins (2, 3) from the circuit.

Title: Coded electric door opening system - has door bell push serving as touch sensor or light sensor
Inventor: LUEBKE HEINZ
IPC: G07C9/00
Filed: 1977-05-11
Abstract: The door-opening system uses a numerical code, but employs the door bell-push instead of a special key board. The code is not easily deduced by an observer. The bell-push, in addition to operating the bell, serves as a sensor, transmitting impulses to a control unit when touched by a finger. Alternatively the bell-push may be shaded and the opening impulses generated with a small light.

Abstract: Between a fusible piece (11), which fuses during the firing of the projectile as a result of the heat generated by air friction, and a percussion spindle (13) is arranged a safety piece (12) which, after the fusible piece (11) has fused, shifts at least partially into the space of the fusible piece and locks in this space. The safety piece (12) then prevents impacts caused by rain drops from being transmitted to the percussion spindle (13). When a solid target is hit, the safety piece (12) breaks and the percussion spindle (13) is actuated. <IMAGE>
